Case Report: Developmental-like skeletal deformities and transient osteosclerosis as rare presentations of primary hyperparathyroidism

This case highlights two key points: first, PHPT can masquerade as developmental skeletal deformity in adolescents, mandating a high index of suspicion and biochemical screening. Second, we describe a novel, self-resolving phenomenon of transient postoperative osteosclerosis, likely representing a reparative bone response following biochemical cure. Successful orthopedic correction before full metabolic normalization underscores the feasibility of staged management with meticulous perioperative care. These observations expand the phenotypic spectrum of pediatric PHPT.
